Connect2id server 5.0.5 adds metrics for Redis backends

Posted 2017-01-02

Connect2id server 5.x received an update to enable retrieval of key metrics on Redis client connection pool usage. If you have a Connect2id server cluster deployed with Redis / AWS ElastiCache as primary in-memory store and want to fine tune your Redis connection pools, these new metrics will provide you with the necessary data.

The new Redis connection pool gauges are made available at the existing /monitor/v1 endpoint, which already collects more than 100 metrics for all sorts of things.

Example Redis client connection pool metrics:

{
    "sessionStore.sessionMap.redisStore.numActiveConnections": {
      "value": 1
    },
    "sessionStore.sessionMap.redisStore.numIdleConnections": {
      "value": 6
    },
    "sessionStore.sessionMap.redisStore.numWaitingForConnection": {
      "value": 0
    },
    "sessionStore.sessionMap.redisStore.maxWaitingTimeForConnectionMs": {
          "value": 15
    },
    "sessionStore.sessionMap.redisStore.meanWaitingTimeForConnectionMs": {
      "value": 0
    }
}

The latest version 6 of the Connect2id server is also going to receive that update later in January. Stay tuned.
